Impact of survey spatial variability on galaxy redshift distributions and the cosmological $3times2$-point statistics for the Rubin Legacy Survey of Space and Time (LSST)

Posted by dbos Stanford

Kavli Affiliate: Eric Charles | First 5 Authors: Qianjun Hang, Benjamin Joachimi, Eric Charles, John Franklin Crenshaw, Patricia Larsen | Summary: We investigate the impact of spatial survey non-uniformity on the galaxy redshift distributions for forthcoming data releases of the Rubin Observatory Legacy Survey of Space and Time (LSST). Specifically, we construct a mock photometry […]

Development of the 220/270 GHz Receiver of BICEP Array

Posted by dbos Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The BICEP/Keck Collaboration, :, Y. Nakato, P. A. R. Ade, Z. Ahmed | Summary: Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on the energy scale of inflation and its potential form. To achieve these goals, one must carefully characterize […]

Targeting 100-PeV tau neutrino detection with an array of phased and high-gain reconstruction antennas

Posted by dbos Chicago

Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Stephanie Wissel, Andrew Zeolla, Cosmin Deaconu, Valentin Decoene, Kaeli Hughes | Summary: Neutrinos at ultrahigh energies can originate both from interactions of cosmic rays at their acceleration sites and through cosmic-ray interactions as they propagate through the universe. These neutrinos are expected to have a low flux […]

The Formation of Milky Way “Bones”: Ubiquitous HI Narrow Self-Absorption Associated with CO Emission

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Shenglan Sun, Ke Wang, Xunchuan Liu, Fengwei Xu, | Summary: Long and skinny molecular filaments running along Galactic spiral arms are known as "bones", since they make up the skeleton of the Milky Way. However, their origin is still an open question. Here, we compare spectral images […]

Flat Chern bands and correlated states in spiral magnet ReAg$_2$Cl$_6$

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Kejie Bao, , , | Summary: We predict the van der Waals monolayer ReAg$_2$Cl$_6$ hosts isolated flat Chern bands at the Fermi level in its $120^circ$ antiferromagnetic ground state. Their flatness and nontrivial topology arise from the cooperative effect of coplanar spin order and strong […]
